Winning tournaments is a long-term process, not something you can solve with one trick, but there are some fundamentals that make a big difference. First, you need to adjust your strategy by stages. Early on, play relatively tight and focus on strong hands and good positions, there’s no reason to risk your whole stack when blinds are small. As the tournament progresses and stacks get shallower, aggression becomes much more important, especially stealing blinds and antes when players are trying to survive.
Second, stack size awareness is key. You should always know roughly how many big blinds you have and play accordingly. With deep stacks, you can afford to see flops and play postflop. With medium stacks, look for good reshove and pressure spots. With short stacks, don’t wait too long, learn basic push/fold ranges and accept that sometimes you bust doing the right thing. Many players lose tournaments simply by becoming too passive when their stack gets low.
Finally, mindset and variance matter a lot. Even very good players lose most tournaments they enter, so focus on making good decisions rather than “winning today.” Review hands, learn from mistakes, and stay patient. If you keep improving your fundamentals and decision-making, results will come over time.
